Hu,
Actually both Win98 and XP work well and is a matter of personal performance.
The CamSoft installation CD offers Win98, ME, NT, 2000 and XP drivers. The motion card has it's own 32 bit DSP processor that handles motion separately from the Windows OS.
You should reduce the number of services and background programs running that are not needed as a recommendation. Most of us here use either Win 2000 or XP but there are 20+ computers here running every OS.
Here is a break down of OS currently being used today.
1. Windows XP 57.55%
2. Windows 98 19.03%
3. Windows 2000 13.60%
4. Windows ME 4.14%
5. Windows 95 2.38%
6. Windows NT 1.14%
7. Macintosh OS 0.78% <less than 1%
8. Linux 0.67% <less than 1%
